• Indirect Text Entry Using One or Two Keys

  Melanie Baljko, Andrew Tam (2006) — Proceedings of the 8th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '06)

  This paper introduces a new descriptive model for indirect text entry — text composition methods where the number of input devices (switches) is significantly smaller than the number of selectable characters. This is the primary text entry paradigm f…

• The Information-Theoretic Analysis of Unimodal Interfaces and their Multimodal Counterparts

  Melanie Baljko (2005) — Proceedings of the 7th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '05)

  This paper applies Shannon Information Theory to formally analyse and quantify the hypothesised benefits of multimodal interfaces over unimodal ones, with particular focus on Augmentative and Alternative Communication (AAC) devices such as Voice Outp…
